How it Works

How Absolute Quantification with Droplet Digital PCR Works

Basic research and clinical research labs have long relied on real-time PCR (qPCR) for its speed, sensitivity, specificity and ease-of-use. Common applications include gene expression analysis, mutation detection and identification of copy number variation to better understand inherited disorders, cancer and infectious disease.

How hTERT-Immortalized Cell Lines Work

Choosing an in vitro model system that faithfully represents the natural physiology of the cell being studied is fundamental to understanding its in vivo function. Cultures of primary cell isolates retain their physiology and karyotype after isolation, but cultures may be difficult to prepare and are susceptible to contamination.

White Papers and Application Notes

Economizing on Viscosity Testing

Rotational viscometers are the most widely used tool in today's QC labs for making viscosity measurements.  Many small changes, like reduction in sample size and shortening the viscosity test time, can lead to significant increase in QC lab productivity.

The Analysis of 1,4-Dioxane for EPA Method 522 and UCMR 3

This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

Concentration of Solutes: Options for the Removal of Solvents from Samples

Solvent removal from solutions is commonly performed in laboratory and production processes. There are a number of different methods that can be used for solvent removal, including evaporation, vacuum concentration, lyophilization, reverse extraction, solute precipitation, and dialysis (solvent exchange).

Determination of Mercury in Nutraceutical Samples Using a Direct Mercury Analyzer

With the expansion of the global nutraceutical market, the spotlight on the analysis of its raw materials is ever increasing. Testing of nutraceutical products for heavy metals like lead, arsenic, cadmium and mercury has gained utmost importance. Extremely low levels of these heavy metals like mercury, in nutraceuticals make its analysis challenging.

Measurement of Gold Nanoparticle Size and Concentration by Spectrophotometry

Although gold nanoparticle production can be controlled to yield specific size ranges, both the concentration and size of nanoparticles must be checked following production. UV-Vis spectrophotometry is an established QC method for this; however cuvette spectrophotometers often require dilution of the nanoparticle solution before measuring, and volumes up to 3 mL.
